Slotting parts together
The greenhouse is based on parts that slot together using 30mm stainless steel screws, as shown
in the diagram below.
Ensure that your screwdriver is
fully engaged with the screw
head when you tighten, so that
you donʼt round off the head of
the screw.
Note the orientation of each
piece in the description;
specifically the closed face.
WARNING Every care has been taken during manufacture to avoid sharp edges or burrs,
however you should still take care when handling metal parts.
WARNING DO NOT USE POWER TOOLS TO SCREW IN THE SCREWS. YOU MIGHT SNAP OFF
THE HEAD, WHICH IS NOT COVERED BY WARRANTY.
Step 1 - Seal the polycarbonate panels (optional)
Twin wall polycarbonate panels act like double glazing for your mini greenhouse, and to improve
the insulation characteristics, it is good to seal the ends of the channels using the provided foil
tape. It also helps prevent bugs from crawling into the plastic.
This step is optional - it can take some time but is recommended.
1. Peel back a couple of inches of the protective foil which covers both sides of the panels,
but donʼt take it all the way off yet.
2. Apply the tape to the end of the panel, covering the flutes.
3. Fold down the sides to seal the tape to the panels.
The white film is on the UV protected side which should face out when you place the panels into
the greenhouse.

Step 2 - Attach the door handles
Do this step first to allow the adhesive tape to cure while you assemble the rest of the
greenhouse. Youʼll fit the doors at the end.
Parts
2 x door handle
2 x polycarbonate door
Fix the door handles to the doors as shown in the drawing
above, using the tape fixed to the handles.
Make sure you have peeled the protective film off the doors
first, the surfaces are clean, dry and free from grease, and that
the UV treated side of the door panels (white film) faces out.
There is a sticker on the right door.

Step 3 - Assemble the base
Parts:
1 x le assembly
1 x right assembly
1 x front base 121cm
1 x rear base 121cm
This step is best done
on a flat surface where
you can easily access
the screws at the
bottom, such as a
table or workbench.
The le and right
assemblies are
interchangeable.
The rear base part has
the single channel
facing up, and the front
has the double
channel facing up.
Slot the le and right assemblies over the
screws on the front and rear base parts and
tighten the screws.

Step 4 - Insert square nuts to side cross bars
Parts
4 x side cross bar 45cm
6 x square nut
See the drawing in step 6 and insert square nuts into
the cross bars.
Two will be for the shelves, and the third will be for
supporting the irrigation pipe (itʼs worth fitting the
nuts now even if you donʼt have the irrigation kit yet).
The inside channel is the one opposite the closed
face.
Step 5 - Insert the side panels and side cross bars
Parts:
4 x clear side panel
4 x side cross bar 45cm
2 x clear side top panel
Peel the protective plastic off both
sides of two side panels, remembering
which side had the white film.
The side with the white film should
face outside; it is the UV treated
side.
Slot the panels into the frame, then
slide the bars, closed face outwards,
down over the clear side panels.
Tighten the screws.
Finish inserting all the side panels and
cross bars in the same way.

Step 6 - Fit right side panel top assemblies
Parts:
1 x Right side panel top assembly
3 x M5 * 8mm button head bolt
3 x M5 square nut
1 x M5 * 10mm button head bolt
Insert the 8mm bolts into the
assembly in positions marked 1,2,3,
and add the square nuts on the
inside, loosely.
Slide the assembly down over the
side panel, inserting the square
nuts into the outer channels on the
uprights.
Screw the 10mm bolt into the square nut which is already in the outside channel of the assembly
and tighten by hand. This will form part of the storm lock (see end of guide)
The front end goes down as far as it will go, and the rear end is flush with the top of the rear
upright (see drawing below).
Tighten the bolts.
Step 7 - Fit le side panel top assembly
Repeat for the le hand side.

Step 8 - Fix lid lier bracket to adapter plate
OPTIONAL - if you have an automatic lid opener
The lid lier bracket is in the lid opener box. (see drawing below for named parts)
Parts:
1 x lid lier bracket
1 x adapter plate
2 x M5 x 8mm button head
2 x M5 nut
Bolt the lier bracket to the adapter plate as
shown, with the nuts on the inside of the
bracket.
Step 9a - Fix bracket to front bar : slot method
Parts:
1 x front upper bar 121cm
1 x bracket assembly from above
2 x M5 x 8mm button head
2 x M5 square nut
Slide two square nuts into the
rear channel of the bar (the side
opposite the closed face). Bolt
the bracket assembly to the front
bar, in the exact centre of the bar.
Step 9b - Through-hole method
If your greenhouse has a front crossbar with no slot, it will have holes drilled in the relevant
places.
Parts:
1 x front upper bar 121cm
1 x bracket assembly from step 9
2 x M5 x 30mm button head
2 x M5 nut
2 x M5 washer
Bolt the bracket to the front bar, through the
two holes using the 30mm bolts, washers
and nuts.

Step 10 - Add the lid prop bolt
This is the pivot bolt for the lid prop.
Note: If your crossbar does not have a slot, you will be provided with longer bolts (M5x40mm)
which go all the way through the bar from the front.
Parts:
1 x M5 x 16mm bolt
1 x M5 nut
1. Put the M5 nut loosely onto the 16mm bolt.
2. Slide the bolt head into the rear channel (same
channel as the lid lier bracket) on the right hand side
(with the lid lier bracket facing away from you)
3. Slide the bolt to 530mm from the right hand side.
4. Holding the thread of the bolt, tighten the nut to lock
the bolt in place.

Step 11 - Insert the front crossbar
Parts
1 x M5 x 30mm bolt
1 x M5 x 40mm bolt
2 x M5 nut
2 x M5 washer
Bolt the front upper bar to the rear of the
brackets on the front of the greenhouse,
using the 30mm bolt on the le and 40mm
bolt on the right.
The longer bolt on the right hand side acts
as a support for the lid prop which you will
add later.
Tighten securely.
Step 12 - Understanding shelf fitting
Study the drawing below to see how the shelves fit. The top shelves are bolted, and the lower
shelves are slotted in. A short section of 4mm tube pressed into the channel prevents the bottom
front shelf from sliding forwards.

Step 13 - Fit the shelf brackets to the frame
Parts
4 x M5 x 8mm cap head bolt
4 x shelf angle bracket
Screw the brackets loosely onto the
cross-bars of the end panels, using the
M5x8mm bolts and the nuts in the channels
of the cross bars.
In the top le crossbar ensure there is one
square nut in between the two shelf angle
brackets.
Step 14 - Fit the upper shelf support bars
Parts
4 x M5 x 8mm cap head bolt
4 x M5 nut
2 x angle aluminium, 121cm
Fix the shelf loosely to the bottom of the
bracket, using another M5x8mm bolt and a
nut underneath.
Push the shelf as far back as it will go,
without obstructing the channel on the
inside of the rear upright; this slot is where
the rear panels will fit.
Tighten all the bolts with the 4mm allen key.
Fit the front upper shelf to the bottom of the angle bracket as shown in step 12, upside down.
Secure two mesh shelves to the supports using cable ties in each corner.
Note: Ensure there is a gap between the two mesh panels to allow the lid lier piston to swing
when the lid opens.

Step 15 - Slot in the lower shelves (4-season only)
Parts
2 x notched shelf support
2 x 4mm plastic tube
2 x mesh shelf
Refer to the drawing in step 12 to see how the lower shelves
slot in.
Push the 4mm tube into the slot on the inside of the crossbar,
to prevent the front shelf support from sliding forwards.
Place the mesh shelves on the shelf supports.
Step 16 - Install rear panels
Parts
2 x rear panel
1 x PVC H-trim 84cm
2 x cable tie
Tip: The edges of the
rear panels can be
squished slightly to
make it easier for them
to slot into rear
uprights.
Insert the two rear panels with the drilled panel on the le. See
your control system setup guide for panel orientation.
●Drop the rear panels into the inner slots of the rear
uprights. Ensure they go fully into the lower base part -
itʼs a tight fit.
●Slide the H-trim between the panels.
●Using the holes in the rear shelf as a guide, punch holes
through the rear panels with the supplied hole punch and
secure the panels to the shelf support with cable ties.
Step 17 - Fit the doors
Parts
2 x polycarbonate door
With handles fitted
Flex the doors slightly and pop them into the channels on the
front base.
The le hand door goes in the rear (inside) channel and the right
hand door goes in the front (outside) channel.
The friction of the sliding doors can be adjusted by revisiting step
11 and adjusting the two outer securing bolts to raise or lower the
crossbar.

Step 18 - Fit the lid prop
Parts
1 x lid prop, 535mm
1 x M5 nyloc nut
Note: The nyloc nut has a little plastic ring
inside to prevent it loosening.
Put the hole in the lid prop over the stud
formed by the bolt on the front crossbar.
Put on the nyloc nut, tightening it just so that
the plastic “bites” the thread. The prop
should be loose enough to move around.
The right hand end of the lid prop rests on the bolt which secures the front bar.
The drawing below shows the view from the inside of the greenhouse.

Step 19 - Lid centre bar
This is easiest done on a flat table or worktop.
Parts
1 x lid rear bar 125cm
1 x lid centre bar 45cm
2 x square nut
Slide the lid centre bar into the lid rear bar, with the closed
side upwards.
Slide the square nuts into the centre bar, in the channel
opposite the closed face. These will hold the automatic lid
opener arm.
When the centre bar is in the middle, tighten the screw at the
back.

Step 20 - Lid side bars
Parts
1 x lid assembly from step 20
4 x square nut
4 x M5 * 10mm
2 x lid sidebar 45cm with corner cubes
Le and Right lid sides will be marked with the corner cubes facing towards you, as per the
drawing at the bottom of this page.
1. Slide two square nuts into the outside channels of the lid sides. These will form the top
bolts for the storm lock as per drawing below.
2. Screw the bolts into the nuts and tighten them by hand to lock them in place.
3. Fit the o-rings over the two bolts on both sides of the lid. This is what the lock will look
like when in operation, holding the lid down:
1. Slide the lid sides into the ends of the lid rear, with the closed side upwards.
2. Tighten the screws.

Step 21 - Insert the lid polycarbonate
Parts
2 x clear lid panel
Slot in the lid polycarbonate sheets.
Youʼll need to flex the lid side bars apart slightly.
Make sure the white UV protected side is upwards. There is a corner taken off the polycarbonate
to fit the corner cubes - ensure that is in the right position before moving to the next step.
Step 22 - Fit the lid front bar
Parts
1 x lid front bar 121cm
2 x 30mm screw
With the closed face up,
slide the lid front bar over
the protruding screw on the
centre bar.
Screw the sides of the lid to
the front bar using the
30mm screws.
Tighten the lid screws firmly.
Step 23 - Fit the ridge to the lid
Parts
1 x assembled lid
1 x ridge
Slide the ridge into the assembled lid as in the drawing above.
